Quartz VS QuartzNet

In java we have found Quartz( Quartz) , Job Runr(Jobrunr) and db-scheduler(db-scheduler) and need to evaluate these for our use case.

Im mit sit what you mean by "not supported", you sure can run MongoDB on Kubernetes. Maybe I'm way off, are you saying that you can't use Quartz (this one: http://www.quartz-scheduler.org/ ?) because it doesn't natively allow you to load from MongoDB and.therefor you can't use it?

Uh this class is even worse, SDF is not a thread safe date formatter, so it never should be `final static`. `releaseDate` and `new Date()` will be ignorant of summer/winter time changes. For such scheduling one should use Quartz https://www.quartz-scheduler.org/

Have a look at http://www.quartz-scheduler.org/ If you're using Java

Long time I used http://www.quartz-scheduler.org which worked nicely, I wonder why Scala does not seem to have something standard for this.

Quartz Scheduler

We have a separate service for running cron jobs. It uses Quartz (http://www.quartz-scheduler.org/) and it has a REST API that we use to submit new jobs. It's easy to set up and all you need is a database. You definitely need a database in order to synchronize across different containers.

I would agree with using Job over Queue. Therefore I would recommend looking at Quartz.Net https://www.quartz-scheduler.net/

You can use something like https://www.quartz-scheduler.net/ to create multiple recurring jobs based on the definition you load from a DB.

Or use an existing open source scheduling solution like https://www.quartz-scheduler.net/

If you're interested in using Quartz, you can check out their GitHub repo here: https://github.com/quartznet/quartznet. They also have extensive documentation available on their website: https://www.quartz-scheduler.net/documentation/index.html.

You should use an actual scheduler. https://www.quartz-scheduler.net/

Better to use a framework like Quartz.NET for scheduling background tasks. How it works inside the box I have no idea, but I have used it extensively in my web applications, and those background tasks run 24/7, come hell or high water. It's a good library, and it's easy to use.
